A recent poll by Centre for Strategic and International Studies (CSIS) showed an increase on President Joko Widodo's approval rating over the last years.

"Every year, the level of public satisfaction rises with the performance of the current government," said CSIS political analyst Arya Fernandes at Pakartu Center Building, Jakarta, Tuesday.

In 2015, 50.6 percent of respondents were satisfied by Jokowi and Vice President Jusuf Kalla's work where in 2016, it hiked up to 66.5 percent. This year, the number reaches up to 68.3 percent.

The survey itself was conducted on 1,000 respondents aged 17 years and over in 34 provinces in Indonesia. The research method used was random sampling with 3.1 percent margin of error and 95 percent confidence level. The data was based in the number of valid samples of respondents interviewed on August 23 to 30, 2017.

The think-tank agency measured the perception of the current government's performance in three sectors: economy, law enforcement and maritime.

In the field of economy, the public satisfaction grows from 54.8 percent last year to 56.9 percent in 2017.

The law enforcement under Jokowi were praised by 64 percent of the respondents, increasing slightly from 62.1 percent in 2016. The support to Corruption Eradication Commission (KPK), encouragement on police institute reformation, and judicial mafia eradication by the government are believed to boost public optimism in the law enforcement.

Scoring from 63,9 percent last year to 75,5 percent this year, Jokowi's work in the maritime sector were lot appreciated with the improvement in physical development.

"The perception increases significantly in infrastructure, such as sea toll roads and ports," said Arya.

The strengthening of maritime defense however is also one of the factors of the rapid upturn in public's perception on government's maritime sector, according to Arya.
